BLOCK FOR HAY-BALERS.

Specification of Letters Patent.

Patented May 8, 1917..

Application filed January 25, 1916. Serial No. 74,211.

To all whom it may concern:

Be it known that I, WILLIAM M. BRUSH, a citizen of the United States, residing at Brule, in the county of Keith and State of Nebraska, have invented certain new and useful Improvements in Blocks for Hay- Balers, of which the following is a specification.

This invention has relation to certain new and useful improvements in hay balers and has for its primary object, the provision of an improved form of end block which will be of simple construction and highly efficient in use.

Another object of the invention resides in the provision of an end block of this character which will take the place of the old form of end board now in general use and which will be of such construction that the wires may be readily withdrawn or inserted as desired.

With the above and other objects in view, the invention resides in the novel construction, combination and arrangement of elements as hereinafter specifically set forth, pointed out in the claims and shown in the accompanying drawings in which Figure 1 is a fragmentary side elevation, partly in section,

Fig. 2 is a view similar to Fig. 1 looking at the opposite face of the end board,

Fig. 3 is a vertical transverse section through the complete device,

Fig. 1 is a horizontal transverse section substantially on the plane of line 4& of Fig. 2 looking in the direction indicated by the arrows, and,

Fig. 5 is a detail transverse vertical section of a slightly modified form of the invention- Referring; more particularly to the drawings, in which similar reference characters designate corresponding parts throughout the several views, 1 designates the central or body portion of the block which may be formed of wood or any other suitable material and which has the transverse upper and lower end members or strips 2 secured to its opposite side faces while the outer transverse members or strips 3 are also secured to the outer faces of said main or The strips 2 and 3 are preferably formed of the same material as the main or body member 1 and are positioned with the grain of the same at right angles to the grain of the main or body member 1. The upper and lower strips 2 are preferably arranged in such manner as to leave transverse spaces 4 between the upper strip 2 and the uppermost strip 3 and also between the lower strip 2 and the lowermost strip 3.

Within each transverse recess is secured an angle iron 5 having one angle secured in the bottom of said recess a. It will be un derstood that the angle iron 5 may be secured in position by any suitable means, as shown at 6 and each angle iron 5 is positioned so that its remaining angle is engaged against the uppermost or lowermost wall of the recess 4, depending upon the recess within which it is positioned. It will also be understood that each angle iron 5 has suitable end extensions 7 which are turned inwardly to close the opposite ends of the recess a, as clearly shown in Figs. 1 and 2 of the drawings.

A bearing plate 8 is also secured against the inner wall of each recess 4L opposite the last mentioned angle of the angle iron 5 to form one wall of the wire accommodating slot 9. The opposite wall of the wire accommodating slot is formed by one angle of a pivoted or hinged angle iron 10. Thepivoted or hinged angle iron '10 is provided upon one edge with the hinge lugs 11 which are engaged in suitable recesses 12, said lugs 11 having suitable heads 13 formed upon their free ends to prevent the same from being withdrawn from the recesses 12. This angle of the angle iron 10 is provided upon its inner face with one or more lugs 11- around which are engaged one end of the springs 15 which have their opposite ends bearing against the second mentioned or outer angles of the angle irons -5, thereby normally retaining the angle irons 10 in set position to close the outer edges of the wire accommodating slots 9, as clearly shown in Fig. 3. This will prevent the binding wires from being accidentally withdrawn from the wire accommodating slots 9. The remaining angle of each angle iron 10 serves to close the outer face of the recess 1 within which it is positioned and this angle of the angle iron 10,.is normally spaced from the outer edge of the angle iron 5 over which it is positioned, as will be readily understood by referring to Fig, 3 of the drawings. It will also be understood by referring to the drawings, that the angle irons 10 are provided with suitable end flanges 16 outwardly of the end extensions 7 and flush with the vertical edges of said main or body member 1 and the strips 2 and 3. It will further be understood that the end extensions 7 are of such size as to permit swinging movement of the angle irons 10 upon the lugs 11.

Upon one side of the block, as shown in Fig. 1, 1 provide only one spring 15 for retaining each angle iron 10 in normal position while upon the opposite side of the block, as clearly shown in Fig. 2, I provide two springs 15 for each angle iron 10. The block is also marked so that the operator of the baler may tell which side to place toward the plunger, it being necessaryl to place toward the plunger the side of the block having two springs for each angle iron 10. The binding wires are then engaged properly and when .a bale is to be withdrawn, the wires engaged around the same may be readily withdrawn from the wire accommodatingslots 9 in the outer side of the block without danger of withdrawing the block or moving the same out of its proper position. It will be evident that as the wires are withdrawn from the outer side of the block, the angle irons 10 swing upon the lugs 11 and compress the springs 15 which will immediately act to return the angle iron 10 to normal position. It will further be evident that owing to the construction and arrangement of the angle irons 5 and 10 and the provision of the springs 15, the hay will be prevented from entering either the recesses 4 or the wire accommodating slots 9 and thereby interfering with proper operation of the baler.

In Fig. 5 I have shown a slightly modified form of the invention, in which the channel irons 5 areemployed and secured in the recesses 4:, as clearly shown, with their central portions engaged against the inner walls of said recesses 4, while the bearing plates 17 are secured against the outer walls of said recesses 1C. The inner angles of the channel irons 5 are extended to the bearing plates 17 while the outer angles of said channel irons 5 are spaced slightly from the bearing plates 17 to provide the wire entrance and exit slot 18. The inner angles of the channel irons 16 are provided with suitable recesses 19 within which are engaged the lugs 20 projecting from the inner edge of the pivotedplate 21, the outer iongitudinal edge of which is normally held in engagement with the bearing plate 17 adj acent which it is positioned and also adjacent the wire entrance and exit slot 18, by means of a suitable spring or springs 22 bearing against the plate 21. The springs 22 have one end engaged around suitable support ing lugs projecting from the inner face of the main angle of the channel iron 5 within which the plate 21 is positioned. Each plate 21 is also provided with suitable triangular end extensions 2 1 projecting into the channel irons 5"to' limit inward swinging movement of said plates 21 and also prevent withdrawal of the same by way of the slots 18. A binding wire accommodating recess 25 is provided between each plate 21 and the bearing plate 17 opposite the same. It will be understood that in this form of the invention, the binding wires may be inserted and withdrawn in the same manner as in the preferred form and furthermore that the springs are preferably arranged in this form as in the same manner as the preferred form.

lVhile the preferred embodiments of the invention have been shown and described, it will be understood that minor changes in the details of construction and arrangement of the parts may be resorted to within the scope of the appended claims without departing from the spirit of the invention or sacrificing any of the advantages of the same.
